Introduction:
Eggs are a favourite food item in many homes all around the world because of their variety and nutrient-rich richness. In countless recipes from custards and cakes for dessert to scrambled eggs for breakfast, eggs find a place in all cuisines. Although most people keep eggs in their refrigerators, it’s important to realise that, given the correct circumstances, these little miracles can continue to be fresh and of high quality without refrigeration.
In this article, we’ll look at the elements that affect eggs’ shelf life and offer advice on how long they can be kept out of the fridge without being unsafe to eat.
Understanding the Protective Design of the Egg
Let’s first examine the specifics of storage before learning more about an egg’s distinctive structure. The outer shell and the inner membrane are the two layers that naturally surround and protect each egg. These coverings aid in preventing the egg from being contaminated from the outside and preserving its contents.

Egg Shelf Life Influencing Factors:
1. Freshness at Purchase: An egg’s shelf life is mostly influenced by how fresh it was when it was purchased. Because they have undergone less processing and have a shorter supply chain than commercially produced eggs, eggs from local farmers or from farmers‘ markets frequently have a shorter shelf life.
2. Temperature: Egg storage depends greatly on temperature. In general, eggs stored in cooler environments last longer. As temperatures rise, there is an increased risk of bacterial development and deterioration.
3. Humidity: High humidity can reduce the quality of eggs by encouraging the growth of germs and mould. It’s crucial to keep eggs in a dry environment.
4. Cleanliness: Eggs can absorb bacteria and odours from their environment since they are permeable. Eggs that have been infected or are dirty have a lower shelf life and may become unsafe to eat even before they have passed their expiration date.
5. Egg Washing: In some nations, eggs are cleaned to remove any potential contamination before being sold. The egg’s natural protective cuticle is removed during this process, however, which increases its susceptibility to spoiling. Eggs that haven’t been washed last longer, even when not refrigerated.
How long may eggs be kept out of the fridge?
Contrary to popular opinion, eggs can be kept for a long time without refrigeration as long as certain requirements are met:
1. Unrefrigerated Shelf Life: Fresh, unwashed eggs can be kept for up to two weeks without refrigeration in conditions of moderate temperature (about 70°F or 21°C) and low humidity.
2. Optimal Storage: To extend the shelf life of unwashed eggs, keep them out of direct sunlight, intense odours, and other contaminants in a cool, dry location.
3. The Water Test : A quick water test can be used to determine whether an egg is still fresh. In a bowl of water, submerge the egg; if it sinks and lays horizontally, it is fresh. It’s a little older but still okay to eat if it sinks but stands on one end. Discard it since it has probably gone bad if it floats.
4. Extended Storage: Refrigeration is still the best choice for storage that lasts longer than two weeks. Commercially produced eggs are frequently cleaned and maintained in a refrigerator, where they should be kept to preserve their freshness and safety.
Frequently Asked Questions (FAQ) About Eggs and Their Storage
How long can eggs be kept at room temperature?
Fresh, unwashed eggs can be kept unrefrigerated in an area with temperatures about 70°F (21°C) and low humidity for up to two weeks. Refrigeration is advised, though, for long-term storage and to assure safety.
How should eggs be kept while not refrigerated?
Place eggs in a cool, dry area away from direct sunshine, intense odours, and other contaminants to preserve them without refrigeration. It’s best to use an egg carton or other container with sufficient airflow. Before storing the eggs, avoid washing them because this can destroy the cuticle, which normally protects the egg.
Can eggs that have been left out at room temperature be refrigerated?
Eggs left out at room temperature for longer than two hours should normally not be refrigerated. At room temperature, bacteria can grow very quickly and may result in foodborne diseases. Use the water test to ensure their freshness or think about throwing them away to be safe.
Are eggs better to store unwashed and not refrigerated?
Unwashed eggs do really have a natural protective coating that keeps the eggs fresh and prevents bacteria from getting inside. Compared to washed eggs, they are therefore safer to store for brief periods of time without refrigeration.
What is the freshness of eggs water test?
The water test is a quick and easy way to determine how fresh an egg is. In a bowl of water, submerge the egg; if it sinks and lays horizontally, it is fresh. It’s a little older but still okay to eat if it sinks but stands on one end. If the egg floats, it has probably gone bad and should be thrown away.

Can eggs become spoiled before they expire?
In particular, if they are not maintained properly or if they were contaminated during handling, eggs might go bad before their expiration date. Before utilising an egg that is getting close to its expiration date, always test the water or look for any strange smells or discolorations.
How long do eggs need to be kept cold?
Commercially produced eggs can be safely kept for 3 to 5 weeks after their packing date when kept in the refrigerator at a consistent temperature of 40°F (4°C) or lower. For more precise instructions, always check the expiration or best-by date on the box.
Can eggs be kept frozen for a long time?
You can freeze eggs for longer-term storage, yes. The eggs must be cracked into a freezer-safe container, lightly whisked, and the container must be marked with the date. It is safe to keep frozen eggs for up to a year.
Can whole eggs be frozen in their shells?
It is not advisable to freeze whole eggs in their shells because the expanding ice may cause the shell to fracture and perhaps contaminate the egg. If you intend to freeze the contents, always crack the egg and preserve it.
How can I determine whether an egg is bad?
Use your senses to assess if an egg has gone rotten. Look out for any strange odours or a sulphurous smell. Check the egg for any blemishes or unappealing features. If in doubt, use the water test to determine how fresh it is.
Conclusion
Eggs are a fantastic food source that are highly valued for their nutritious content and adaptability in the kitchen. While refrigeration is the preferred method of egg storage, when kept properly in a cool, dry location free from pollutants, eggs can retain their freshness and quality for up to two weeks. Fresh, unwashed eggs are particularly resistant to this.
However, refrigeration continues to be the most dependable choice for long-term storage and to maintain safety, especially for professionally produced eggs. Understanding these storage recommendations as consumers enables us to make sensible decisions, reduce food waste, and yet enjoy the benefits of eggs. Therefore, eggs will continue to surprise us with their sweetness and versatility whether you choose to store them in the refrigerator or for a short period of time without refrigeration.
